Definitions
- the invention relates to a rolling element screw drive according to the preamble of claim 1.
- a corresponding rolling element screw drive with a one-piece deflection element is, for example, from FIG DE-C-29 14 756 known.
- Deflection elements as described above, are also made DE-C-24 37 497 known. Furthermore, a prospectus from A. Mannesmann, Remscheid, referred to with the title "AM Works Standard 26" which is not the manufacture of a deflection piece with one in the circumferential direction completely closed deflection channel emerges by means of an end mill, which has spherically attached cutting edges at the tip.
- the deflection element can, for example, be a deflection element main part and have at least one deflection element secondary part, wherein the deflection element main part in addition to the boundary of the diversion channel performs other functions, for example the attachment of the deflecting element on the threaded nut.
- the deflecting element parts can for example jammed together or by means of at least one one of the deflection element parts arranged pin, which in a corresponding Engages recess of the other deflecting element part, be connected. Are several such pin-recess pairs Not all pens need to be on the same Deflection element part to be arranged.
- At least one pin-recess pair can be designed such that the pin only under pressure in the Recess can be introduced so that there is a press fit.
- This type of connection can also be used for the purposes of the present application be regarded as "jamming" of the deflecting element parts. in principle however, it is also conceivable for the deflecting element parts to be closed together stick together.
- a particularly safe way of mounting the deflecting element on the Thread nut consists in the screwing of these two parts.
- the in this case, at least one deflection element secondary part can be the result of Attachment of the deflection element main part to the threaded nut be kept.
- Rolling element screw drive A special development of the deflection elements of the invention Rolling element screw drive can be seen in the fact that the penultimate thread revolution of the thread channel delimiting on the thread nut side Thread surface at least partially from the outer surface of the deflecting element is trained. In this way, the deflecting element in the Take up a relatively large installation space without the threaded nut Impair function. This also allows the deflecting element Training of large diameter rolling elements to be robust.
- the deflection element can also be a Have recess in which a holding element is inserted, which consists of is made of a harder or softer material than the deflecting element, the extending in the direction of the depth of the recess Dimension of the holding element is dimensioned such that that in the Recess received holding element further out of the recess protrudes than that between the deflecting element and this assigned receiving recess of the threaded nut provided play equivalent.
- a Holding element from the recess between about 0.05 mm and about 0.4 mm, preferably about 0.2 mm, protrude.
- the holding element can be a ball.
- This Ball can be made of a material that is both softer than can also be harder than the material of the deflecting element. So it can Ball made of NBR (Nitrile-Butadiene Rubber) or made of hardened steel.
- NBR Nirile-Butadiene Rubber
- the recess in a partial surface of the outer surface of the deflecting element is provided which to that partial surface of the outer surface of the Deflection elements is arranged essentially opposite, in which the end section of the deflection channel leading to the threaded channel opens, so the deflection element due to the bias by the holding element be pressed against the threaded nut such that a essentially flush transition from the thread channel to the deflection channel results.
- the deflecting element can further have a rolling element lifting lug, which for engagement in a Thread rotation of the threaded spindle is determined.
- the outer contour of the lifting attachment essentially the contour of the threaded surface the threaded spindle must be designed accordingly, preferably such that they are in the operationally assembled state of the rolling element screw drive essentially equidistant to the contour of the bottom surface of the Thread rotation of the threaded spindle is arranged.
- the return channel from the interior of a one-piece or multi-piece Return pipe with preferably formed by refractive pipe wall which is inserted in a return recess of the threaded nut, but preferably the boundary walls of this return recess not touched.
- the use of such a return pipe has the advantage that the manufacture of the threaded nut is simplified because it is only one to have return holes dimensioned with relatively large tolerances needs. Another advantage of using such a return pipe represents the associated reduction in noise represents.
- Linear bearings are known from EP-B-0 472 167 and US-A-5,800,064, in which a return pipe arrangement or a slotted return pipe is used. The use of such is in rolling element screw drives Return pipes not yet known.
- the return pipe can, for example, thereby with the deflection elements be connected to at least one of the longitudinal ends of the return pipe engages in a ring recess formed on the deflection element, wherein the return pipe may preferably be clamped to the deflecting element can.
- rolling elements are preferably balls.
- other types of rolling elements are also intended, for example Roles, not to be excluded.
- a rolling element screw drive is generally at 10 designated. It comprises a threaded spindle (not shown) and one Threaded nut enclosing threaded nut 12.
- the threaded spindle is on its outer peripheral surface with a helical in the direction of Provide axis A running thread surface.
- the threaded nut 12 on its inner peripheral surface 12a helically continuing thread surface 14.
- the thread surface the threaded spindle and the threaded surface 14 of the threaded nut 12 together form a helical thread channel 16.
- At the end regions 16a and 16b of the threaded channel 16 is on the Threaded nut 12 each have a deflecting element 18.
- the rolling elements running in the threaded channel 16, for example balls, from the threaded channel 16 and to pass through a deflection channel 20 to a return channel 22.
- the rolling elements reach the other channel through the return channel Longitudinal end of the threaded channel 16, where it from the other Deflection element 18 can be returned to the threaded channel 16.
- the threaded channel 16, the two deflection channels 20 of the deflection elements 18 and the return channel 22 together form an endless circulation channel 24, in which an endless row of rolling elements is received.
- the deflection elements 18 of the rolling element screw drive according to the invention 10 formed in two parts. So that includes Deflection element 18, a main part 26 and a secondary part 28, preferably both are made of plastic as injection molded parts. The two Deflection element parts 26 and 28 jointly delimit the deflection channel 20 of the deflecting element 18.
- both the main part 26 comprises one Deflection channel partial boundary surface 30, which extends from one of the return channel 22 near mouth opening 20a of the deflection channel 20 to one the mouth opening 20b of the deflection channel 20 near the threaded channel 16 extends, as well as the secondary part 28 a Umlenkkanal partial boundary surface 32, which are between these two orifices 20a and 20b of the deflection channel 20 extends.
- the two deflection element parts 26 and 28 can in principle attached to each other by gluing. However, to an impairment of the deflection channel through between these two deflection element parts 26 and 28 prevent adhesive emerging in the deflection channel 20
- the two deflecting element parts 26 and 28 close in Essentially flush with each other so that one is essentially smooth and step-free or projection-free boundary surface 20c of the Deflection channel 20 results.
- connection of the two deflecting element parts 26 and 28 can for example in the course of fastening the deflecting element 18 or the deflecting element parts 26 and 28 are brought about on the threaded nut 12.
- the deflection element main part 26 includes a Through hole 34 through which a bolt (not shown) can be passed and screwed to the threaded nut 12.
- the through hole 34 is for receiving the head of the screw bolt 3 at one of its ends with an enlarged recess 34a educated.
- the outer surface of the deflection element main part 26 is a blind hole 36 in the Deflection element main part 26 is provided.
- this blind hole 36 at Mounting the deflection element 18 on the threaded nut 12 a (not shown) Retaining or preload ball inserted.
- the depth of the Blind holes 36 and the diameter of the retaining or bias ball dimensioned so that the ball emerges from the blind hole 36 protrudes slightly more than the game between the deflecting element 18th and the recess 12b of the threaded nut intended to receive it 12 (see Fig. 4) corresponds.
- the deflection element 18 must therefore some force can be pressed into its receptacle 12b.
- a retaining or preload ball made of a harder material is manufactured as the deflection element 18, for example hardened steel, the blind hole 36 and in particular the bottom of the ball is elastic or plastically deformed.
- the ball is made of a softer one Material manufactured as the deflection element 18, for example NBR (nitrile butadienes Rubber), the ball is deformed elastically or plastically.
- the deflection element 18 in the receptacle 12b is biased in such a way that the mouth opening close to the threaded channel 16 20b of the deflection channel 20 with the threaded channel 16 in such a way Engagement that is pressed for in the circulation channel 24th recorded rolling elements an essentially smooth transition between Threaded channel 16 and deflection channel 20 results.
- the deflection element 18 has a rolling element lifting attachment 40 on.
- the outer contour of this approach 40 is essentially in adaptation to the shape of the thread revolutions of the threaded spindle, where however, care was taken to ensure that the rolling element lifting attachment 40 and in particular its lifting nose 40c in the assembled state ready for operation of the rolling element screw drive 10 is essentially equidistant from the bottom surface the thread revolutions of the threaded spindle runs.
- the rolling element lifting attachment 40 is composed of a first extension part 40a formed on the deflection element main part 26 and a second extension part formed on the secondary element 28 40b together.
- the return duct 22 is not immediately on the threaded nut 12 formed, but in one of them separately trained return pipe 42 which with play in an axial passage 12c the threaded nut 12 is received.
- the mouth opening 20a of the deflection channel 20 like a ring shoulder surrounds. 1
- the recess 44 and the return pipe 42 are one on the other in this way matched that the return pipe 42 on the deflecting element 18 kept essentially free of play, preferably jammed with it is. Furthermore, the deflection channel 20 and the return pipe 42 have the same inner diameter or the same clear width, so that the deflection channel 20 and the return channel 22 are essentially flush and Connect to each other without steps.
- the boundary walls of the axial passage 12c has the advantage that the radial with respect to the axis A Position of the return channel 22 not only during assembly, but also in Operation of the rolling element screw drive 10 easily adapts to the exact Positioning the deflection elements 18 and in particular the position of the Mouth opening 20a of the deflection channel 20 can adjust so that always a smooth and essentially stepless transition between the deflection channel 20 and return channel 22 is guaranteed.
- Another advantage of Use of the return pipe 42 is reduced in the accompanying To see noise development.
- deflection element 18 Another special feature of the deflection element 18 according to the invention is see a portion 48 of its outer peripheral surface as part a thread flank of the penultimate thread revolution 14a of the thread surface 14 is formed.
- the surface 48 of the deflection element 18 is again partly (at 48a) on the deflection element main part 26 and partly (at 48b) formed on the deflection element secondary part 28.
- Form deflection element 18 particularly robust and stable. To prevent, that the deflecting element 18 due to the engagement with the in Threaded channel 16 rotating rolling elements exposed to increased wear at least the part of the thread flank of the thread revolution 14a, in which the thread flank partial boundary surface 48 of the deflecting element 18 is arranged, specifically relieved by "shifting" the thread revolutions, so that the rolling elements can roll on the surface 48 without load.
